Do you really need Mac antivirus software? The answer to that and other frequently asked questions about Mac viruses and Macintosh antivirus software is provided in this Mac virus FAQs.
1. Do I really need Mac antivirus software?
If you never connect your Mac to the Internet, the answer is no. But if you do use the Internet, the answer is yes. And since most everyone is online these days, that means that the majority of Mac users need to consider installing
Macintosh compatible antivirus software.
2. Are there any real Mac viruses out there?
Some try to answer this question literally, based on the strict definition of 'virus' - i.e. malicious software that infects other files. But the term 'virus' is used much more loosely these days and in that context refers to malicious software in general (or what the industry terms 'malware'). The answer also depends on the version of the Mac operating system (OS) in question. While Windows tends to be essentially the same "under the hood", the various flavors of the Macintosh OS vary widely. Thus the answer to the question is Yes, there are real Mac viruses out there. But whether you are vulnerable or not depends on the OS. As for malware in general, it's an even stronger Yes.As with any software, the answer depends on you and your specific needs.

4. Do Macs need patching?
Modern exploits target vulnerabilities in Web applications such as Flash, QuickTime, and Adobe Reader. And all browsers are susceptible. Threats that run within the context of the browser or that target a Web application such as Adobe Flash, Apple Quicktime, or Adobe Reader can also impact Mac users. Even if no malware is physically installed, successful exploit could be used to launch
man-in-the-middle and other redirection attacks - a rising concern on the Web today.
5. What's this downstream protection I keep hearing about?
Some vendors of Mac antivirus software focus more on what is known as "downstream protection". Briefly, that's designed to protect Windows users from Windows-based malware that is sent from a Mac user. As an example, Sally uses Mac OS X 10.5 (Leopard). She receives an email with an infected attachment. That particular attachment can't infect her Mac, but if she sends it on to Bob, a Windows user, and Bob opens the attachment, his system could be protected. Downstream protection means that the Macintosh antivirus scanner is scanning for Windows-based malware.Mac antivirus software is in short supply and the options for free Mac virus scanners is even more limited. Still, there are a couple of free Mac antivirus software available. For details, see:

7. What about spyware targeting the Macintosh?
Spyware is a type of malicious software (malware) that monitors computer use. Depending on how over zealous the marketing is, the term spyware can refer to anything from benign cookies to dangerous keyloggers. In general, spyware is a Web threat and as such Mac users are vulnerable.8. Can my iPod and iPhone be infected?
Yes. When Apple introduced application support for the iPod and iPhone touch, they opened the door for malware that specifically targets these devices (or, rather, the applications running on those devices).
